What types of aquarium stands are best to use?
Since saltwater is extremely heavy (8.6 lb/gallon), it is important to use the sturdiest aquarium stand you can afford. Many aquarium manufacturers make very solid wooden cabinets that can easily support the weight of the aquarium while also providing much-needed storage inside for sump system filtration. Many companies make a compatible stand for the tank that they are providing and their warranty requires that the tank they sell be on the stand they recommend (this is not always the best option).
For the largest of aquariums, welded metal stands dressed in decorative wood for esthetics should be used. This will ensure that the tank will be supported for years to come and replacement of the stand will not be necessary.
